demonstrates 1003.dem.003 Louis J. Sheehan, Esquire

A taped interview with the Greater Manchester Police demonstrates this lack of knowledge:

Police Officer: I'll just remind you of the date of this lady's death — 11th May '98. After 3 o'clock that afternoon, you have endorsed the computer with the date of 1st October '97 which is 10 months prior, 'chest pains'.

Dr. Shipman: I have no recollection of me putting that on the machine.

Officer: It's your passcode; it's your name.

Shipman: It doesn't alter the fact I can't remember doing it.

Officer: You attended the house at 3 o'clock. That's when you murdered this lady. You went back to the surgery and immediately started altering this lady's medical records. You tell me why you needed to do that.

Shipman: There's no answer.

In another recorded interview, Detective Constable Marie Snitynski also demonstrated how Shipman's computer trapped him. Following her advising the doctor he had killed a patient (73-year-old Winnifred Mellor) with morphine overdose, then altered records to show a history of angina and chest pains, the police officer continued her interview:

Police Officer: The levels were such that this woman actually died from toxicity of morphine, not as you wrongly diagnosed. In plain speaking you murdered her...One feature of these statements from the family was they couldn't believe their own mother had chest pains, angina and hadn't been informed.
